After this puzzle was released (and about once an hour until teams solved the puzzle), teams received a spam message.
In this spam, there is a 5-digit number (17548) in the subject line and various dollar amounts in the text. The dollar amounts correspond to the amounts raised by the winners of the APO Big Screw and Ugliest Manifestation on Campus charity fundraisers in the past few years. (APO, hence all the words that start with APO.) When you take the specified letters out of the people's names, you get the message HAIKU WITH THE SPAM NUMBER SECOND WORD:
HA $932.63 Hale V. D. Bradt 1,2 2001 Big Screw IK $493.76 Ken J. Lin 6,1 1993 UMOC UW $335.05 Matthew H. Braun 12, 7 1998 Big Screw IT $291.40 Eliot S.

Dorow 10,7 1997 Big Screw RD $979.97 Neal Dorow 8,6 2000 Big Screw
The names can all be found in the relevant issues of the Tech (or on APO's web site). And yes, Neal (H.) Dorow is listed with his middle initial in 1997 and without in 2000, in both places.
The haiku with the number 17548 in the spam haiku archive is:
gall; to serve greasy SPAM chunks
at fancy dress ball.
The second word, and therefore the answer, is GALL.
